To all whom it may concern:

Be it knoxvn'that l, Assam Assn Gm- WOLD, a citizen of theUnited States, residing at Providence, in the county of Providence and State: of Rhode Island, .have'invented a new and useful Improvement in Flexible-Shingle Machines, of ivliichthe following isaspecification. My invention has reference to an improvement in flexible shingle machines and more particularly to an improvement in a flexible shingle machine for manufacturing I automatically flexible shingles such as is shown in any United States Patent No. 1,2Mfl10, issued to me. August 6, 1918.

The object of my invention is to improve the construction of such a flexible shingle machine, whereby a strip of flexible shingle material, tivo shingles Wide, is fed into the machine intermittently and practically continuously, the strip of shingle material cut lengthwise" and crosswise into shinglesof the required size, the fasteningiivires formed and secured tothe corners of two shingles ,si--

multaneously and the corners of two shingles with the. fastening Wires, bent over and onto the body of the shingles, simultaneously thereby forming underturn'ed flaps, with fas toning Wilt-8S, on the shingles and completing two shinglesautomatically, all, in one operation of the machine. I 1

My improved flexible shinglemachine consists essentially of the following elements, a frame,a drivingmechanism, a

mechanism, a transverse cutting mechanism, oppositely disposed Wire forming and securing mechanisms, oppositely disposed Wire feed reechanisins,oppositely disposed Wire cutting mechanisms, and oppositely disposed shingle corner folding mechanisms In the drawings-A indicates the frame, B the driving mechanism, C the feed mecha nism, D the longitudinal shingle cutting inochanisrn, E thetransverse shingle cutting 'in'echanis n', F, F, oppositely disposed fasteningiwire. forming and securing mechanisms, G, Gr, oppositely disposed Wire, feed mechanisms, H, H, oppositely disposed wire Figure'9 is an enlargedsfaee vievv, partly feed mechanism, a longitudinalcutting cutting mechanisms, 1, I, oppositely disposed shingle ;corner foldingmechanisms .of my improved flexible shingle machine, J a practically continuous strip of flexible shingle 'inaterial K, K, Wire and L thecompleted flexible shingle as shown in my previous patent. r a M The plan of the'frame A is rectangular, it has the necessary bearings and openings for the different operative mechanisms, a fiat .hed l supportedpreferably on legs 2, 2 and I having on each side of the bed raised longitudinal guidevvays 3, 3 for guiding the strip of flexible material J throughthe ma- ,chine, a a a The-driving I mechanism B comprises a transverse main driving shaft 4: rotatably supported in bearings in the frame A. The shaft 4; has bevel gears 5, 5, meshing with bevel gears 6, 6, on angular shafts 7, 7 supported in bearings from the bed 1. The shaft 41 also has a bevel gear 8 meshing with a bevel gear 9 on a'shaft 10 in bearings on the side of the frame A. On the other end of the shaft 10 is a bevel gear 11 meshing with a bevel gear 12 on a transverse shaft 13 supported in bearings in the frame A. On the shaft 13 are bevel gears 14-, 14 meshing with bevel gears 15, 15 on angular shafts 16, 16'supported in bearings from the bed 1. The layout of these driving shafts is shown in Figure 3 and they are for conveying power to the different operating mechanisms of the machine.

The feed mechanism O comprises a transverse lower feed roll 17 on a shaft rotatably supported in bearings in the frame A and extending through an opening in the bed 1. Over the feed roll 17 is a similar upper feed roll 18 on a shaft 19 in hearings on the bed 1 and on the shaft 19 is a ratchet 20. Pivoted on the shaft 19 is a lever 21 having on its upper end a pawl 22 engaging with the ratchet 20. On the lower end of the lever 21 is adjustably secured a connecting rod 23 which is adjustably and pivotally secured at its other end to a crank 24 secured to the main driving shaft 4 of the driving mechanism B, as shown in Figure 1. By this construction the strip of shingle material J is intermittently fed by the feed rolls 17 and 18 into the machine and onto the bed 1.

The longitudinal shingle cutting mechanism D consists of a thin central circular cutter 25 on a shaft 26 in bearings on the bed 1 and extending down through a slit in the bed 1. On one end of the shaft 26 is a sprocket wheel 27 operatively connected to a sprocket wheel 28 on the main driving shaft 4, by a sprocket chain 29, as shown in Figure 1. By this construction the strip of shingle material J is split lengthwise into two strips 30, 30 the width of a shingle.

The transverse shingle cutting mechanism E consists of a transverse cutting blade 31 having a lower cutting edge 32 working in conjunction with the sharp edge of a plate 33 embedded in the bed 1 at the edge of a trans verse opening in the bed 1, as shown in Fig ure 10. The ends of the blade 31 are reciprocally supported in vertical guide standards 34, 34: on the bed 1. Each end of the blade 31 has a trunnion 35 to which is pivotally and adjustably secured the upper end of a connecting rod 36. The lower end of the connecting rod 36 is adjustably secured to an extension 37 on the main driving shaft 1, as

shown in Figures 1 and 2. By this construc-- tion the blade 31 cuts the two strips 30, 30 of the shingle material transversely into two square shingles at each operation of the machine.

Each of the oppositely disposed wire forming and securing mechanisms F, F are set at an angle on the bed 1 and extend transversely over the corners of the shingles, as shown in Figure 2, in a position to insert, form and secure the fastening wires in the required place across the corner of the shingles.

Each of these mechanisms consists of a lower staple forming and guide member 38 hung from the bed 1 and guiding vertically an upper staple forming block 39 and a lower pusher block 40. The upper block 39 has a roll 41 working in a cam groove 42 in a cam 13 on the shaft 7 to raise and lower the block. The upper forming block 39 also reciprocally supports a horizontal slide 4&1 having adjacent its rear end a notch 45 engaging with a continuous cam lip 16 on the periphery of the cam 13. The cam lip 46 is shaped to reciprocate the slide as in the block 39. The lower pusher block 40 has a roll 4L7 working in a cam groove 48 in a cam 19 on the shaft 7. On top of and secured to the bed 1 is a vertical guide standard 50 guiding vertically a lower presser block 51 and an upper forming block 52. A bell crank lever 53 having arms 5 1- and 55 is pivoted to a bearing 56 on the bed 1. The arm 51 has a slotted end 57 in which is a roll 58 on the back of the lower presser block 51. The arm 55 has a roll 59 on its lower end which works in a cam groove 60 in a cam 61 on the shaft 7. A bell crank lever 62 having arms 63 and 64 is pivoted to the bearing 56 on the bed 1. The arm 63 has a slotted end 65 in which is a roll 66 on the back of the upper forming block 52. The lower arm 641 has on its end a roll 67 working in a cam groove 68 in a cam 69 on the shaft 7. Toggle jointed arms 70 and 71 are pivotally secured together at their upper ends and to the upper forming block 52 and at the lower ends to the upper ends of wire forming arms 72 and 73 which are pivotally secured together at their lower ends and to the lower presser block 51, as shown in Figure 41. The wire forming arms 72 and 73 have in their outer edges longitudinal wire grooves 7 1, 7 1, as shown in Figure 5 and the outer edges of these arms are shaped, as shown in Figure 1, to form the ends of the wire into the form as shown in Figure 13. The presser block 51 straddles the arms 72 and 73 so as to press the corner of the shingle down onto the bed 1, at each side-of the place where a wire staple 75, as shown in Figure 5, is pushed through the corner of the shingle.

The cams and operating parts are constructed and timed so that the operations are as follows. The wire K is fed into the mechanism the distance required and the length required out off as will be hereinafter described. The cut'off'piece ofstaple-wire now lays centrally across the openingin the top of the guide member 38, as shown in dotted lines in Figure The forward end of the slide 44 moving downwards over the wire, which is guided downwardsin wire grooves 76, 76, 111 the. guide member38,

forms the wire into a U shaped wire staple.

75. On the upward movement of the lower pusher block "40, the horizontal slide44 re cedes out of the way and inthenext opera.- tion comes back over the next wire staple. The presser block 51 now movies-downonto and presses the corner of the shingle L firmly on the bed 1. The lower pusher block 40 on its upward movement pushes the arms of the wirestaple 75 through an 'openingf in the bed and through thecorner of the shingle to their limit into the wire'g'rooves 74, 74 in the wire forming arms 72 and'73, andqsimultaneously vtheupper fo-rming block 52 moves downwards until the wire forming arms 72 and 73 are in a horizontal position,

thereby forming. the wire staple 75 intoafastening wire 77, on the corner of the shingle, as shown in Figure 13. V

Each of theiwire feed mechanisms consists of a hanger 78 hungfrom the bed1, as shown in dotted lines inFigure 8. Pivoted to the lower endof thehangerj7 8 is a lever 79 having a slotted upper end 80. -A slide 81 havingbifurcated arms 82, 82 is reciprocally supported in horizontal guide ways 83, 83 inthe. underside ofthe bed 1.

Pivoted between the bifurcated-arms 82, 82 is a lever 84 having an upper ofl" center wire biting end 85 and a lower end 86 'on which is a transverse pin 87in the slotted upper free of the wire until the next revolution of the cam, 90. t I g The wire cutting mechanism H consists of a blade 91 having-a transverse ecuttingwedge 92 and secured in the end of a recess 93in the underside of the bedl. Apivotbearing 94 is secured to the underside of the bed ,1. A cut off bell crank lever 95 is pivotally secured to the pivot bearing 94 andhas a short upper horizontal arm 96 to. the end ofwhich is secured a transverse blade 97 having a cutting edge 98 which with the cuttlng edge The out OK of the blade 91 cuts the wire K. hell crank lever .95 has a long lower arm '99 on the end of which is a roll 100 working in a cam groove 101 in a cam .102 on the shaft17.

The cam102 is constructed and timedso that the wire K is out at the time that the wire K isfed the distance: required.

Eachof the oppositely disposed shingle corner folding mechanisms Llconsists of a pivot bearing 103 on the underside of the bed 1. A lever 104 is 'pivotally secured to the bearing 103 and hasa straight lower. arm

105: anda sickle shaped upper arm 106 working'throughan opening 107 in' the bed 1. The lower arm 105 has a U shapedend 108 with rolls 109,109,011 the ends of the arms of the U shaped end 108, which straddlethe peripheral edge of'a cam 110 on the shaft 16. The peripheral edge of the-cam110 is shaped as shown in Figures ,3 and 7 to swing theend of the sickle shaped upper arm 106 of the lever 104 through the opening 107 in the bed 1, at a predetermined time. On the top. of the bed l'is secured a pivot bearing .111 in which is a shaft 112. On the rear end of the shaft ,112 1 is secured a shingle corner holding arm 113 which at a predetermined time extends across thecornerof the shingle, on a line where the corner of the shingle is to be bent over, as shown -in.;Fig-

iuresS, 6 and 7. On theiorward end of the shaft 112 is secured a lever 114 having on. its'lowerend a .roll 115 working in a cam groove 116 in a cam 117 on the shaft 16. Secured to the top of the bed 1 is a pivot bearing 118 in which isla shaft 119. Secured to the'rear end of the shaft 119 is an. arm120 having a slotted end 121. Secured to the' top of the bed 1. is a standard 122 having guide ways. 123, 123 which guide vertically apresser block-124 over the corner of the shingle. On the back of the presser block 124 is a stud 125 working in the slotted end 1210f the arm- 120.; On the forwardend of the shaft 119 is secured a lever 126 which extends through an opening in; the bed 1 and has on its lower end a roll 127 working in a cam groove 128 in a cam 129, on the shaft 16. The-cams and operative parts are constructed and timed as follows. The shingle corner holding arm 113 comes down across the corner of the shingle where the corner is to be bent, as shown in Figures 6 and 7 and stays down until the end of the sickle shaped arm 1% has engagedwith the cornerof the shingle and raised .-the corner of theshingle into a nearly vertical position, when the arm 113 moves upwards out, of the way, i

as indicated in dotted lines in'Figure 7. The

:end of the sickle; shaped arm 106 continues onover the bed 1 until the corner of the shingle is ainythe position as indicated in dotted lines 'in Figure 7 when the presser block 124 comes down and presses the corner of the-shingle firmly aga'inst'the body of the shingle, thereby completing the folding over of the shingle cornerfl The shingle corner nowtforms an underturned' flap 130 on the back of the shingle L, in which is the fastening wire 77, as shown in Figure 12. J 1

The strip of shingle material J comes from. a source of supply, not shown, and goes through the machine underside up.

Each wire K. comes from a source of supply not shown, and is fed into the machine at an angle, as described. v

The operation of the different elements is as follows: With power applied to the pulley of the driving mechanism B, the strip of shingle material J is fed into the machine by the feedmechanism and cut lengthwise and crosswise by the longitudinal and transverse cutting mechanism D and E. The strip of shingle material and the cut off shingles are then held stationary and the fastening wire mechanisms F, F, the wire feed mechanisms G, G and the wire cutting mechanisms H, H come into operation to put the fastening wire 77 into the corner of the shingle. The two forward shingles arenow pushed along by the following shingles, the distance of one shingle, on the next operation of the machine. The shingle corner folding mechanisms I, I now come into operation and'fold the corners of the shingles onto the body of the shingles, as described. As the shingles are completed they are pushed ofl the end of the bed 1 by the following shingles, into a receptacle or onto a conveyer, not shown. After the first operation of the machine, theoperations of putting the fastening wires into the corners of the shingles and folding over the corners of the shingles are done simultaneously. Each of the completed shingles L, L are the same asshown in my United States patent referred to and the'machine completes two of such shinglessimultaneously and automatically, and one operator can tend to one or more of the machines.
